HIV/AIDS epidemics among men who have sex with men (MSM) in Africa, Asia, Latin America and the Caribbean, and the CIS July 18th, 2008 Chris Beyrer MD MPH The Center for Public Health and Human Rights Johns Hopkins Bloomberg School of Public Health
Introduction • HIV epidemic spread among MSM is occurring in both high and low income settings in 2008 • MSM HIV epidemics are underway in Latin America, Asia, Eastern Europe/FSU, and Africa • Many MSM epidemics are occurring in “hidden” contexts of discrimination, stigma, criminalization, rights abrogation and limited HIV surveillance

Individual level determinants for HIV among MSM Unprotected anal intercourse ( risk with receptive UAI) High frequency of male partners (>3 sexual contacts/ week) High number of lifetime male partners (>10) Untreated STI (syphilis, HSV-2) Injection drug use Non injection drugs Methamphetamines Possible risk: Lack of circumcision Mediated through increased sexual exposure
Interventions with known efficacy for MSM Education, behavioral interventions, peer outreach Condom promotion and social marketing HIV VCT STI diagnosis and treatment (syphilis) Structural interventions (closing baths, providing MSM-friendly clinic services)
Elevated Risk for HIV Infection among MSM in Low and Middle Income Countries 2000-2006: A Systematic Review Stefan Baral, Sifakis F, Cleghorn F, Beyrer C. PLoS Medicine, Dec. 1, 2007
Search Protocol Potentially relevant studies identified and abstracts screened for retrieval from international conference searches (n=779) Potentially relevant studies identified and abstracts screened for retrieval from literature Searches (n=1395) Duplicates excluded (n=255) Reports excluded based on abstract due to lack of quantitative data, geographical context, sample size, self-reported HIV status. n=1280 Abstracts excluded based on abstract due to lack of quantitative data, geographical context, sample size, self-reported HIV status. (n=475) Full texts retrieved for further analysis (n=115) Conference abstracts retrieved for further analysis (n=49) Reports excluded based on lack of HIV prevalence data, inability to calculate country population HIV prevalence (n=93) Abstracts excluded based on inability to find background data on specific country HIV prevalence, inability to find further information on statistical methods (n=6) Studies retrieved that were coordinated by EuroHIV and commissioned by European Union (n=16) Unique studies retrieved from US Census Bureau Database for HIV/AIDS (n=2) 83 studies from 58 unique reports describing data from 38 countries used in meta-analysis
Results Total of 83 publications from 38 countries on HIV in MSM US Bureau of Census and UNAIDS data to estimate general population levels of HIV in adults aged 15-49 Total sample: 63,538 individual men Pooled OR for HIV infection in MSM: 19.3 In very low HIV Prevalence settings (<1/1000 adults with HIV) Pooled OR for MSM was 58.4 In high prevalence settings (> 1/20 infected) Pooled OR for MSM was 9.6

What do these data tell us? Why are we seeing such high HIV rates in MSM in 2008?
Implications • MSM understudied in many emerging HIV epidemic contexts: MSM not included in national HIV surveillance in majority of low and middle income countries • Africa most markedly understudied region • Urgent need to include MSM risks in national HIV/AIDS surveillance, in STI measures, and particularly where culturally difficult • Evidence based and rights based approaches to HIV both mandate that there be non-discrimination in services, access,and funding
Recent Work • Rapid assessment among MSM in Moscow and St. Petersburg – January 2008 • Four country Epi Probe study among MSM in Southern Africa

African MSM Research • Research Objectives • Demonstrate need for targeted HIV prevention expenditures from regional, national, and international funding agencies • Inform prevention strategies • OSISA/SHARP/JHSPH HIV Prevalence Probe Design • 200 Men in each of 4 different sites in Southern Africa (n=800 total) • Gabarone, Lilongwe, Windhoek, Cape Town townships • Community partners at each site who have received grants to execute study with support • Country approval being sought in collaboration with local academic partners • Anonymous two-sided, one page survey instrument and HIV rapid kit testing using oral fluid samples • Survey instrument briefly addresses baseline characteristics, HIV related knowledge, HIV risk status, and human rights contexts
HIV Prevalence Study of MSM in Malawi • Background • First evaluation of HIV among MSM in Malawi • Methods • Community-based study of 200 MSM with LGBT rights partner • Results • HIV Prevalence 21.4 % • Background HIV prevalence among men is 11.5% • Odds Ratio for HIV infection among MSM is 2.08 (95% CI 1.49-3.02) • Risk Factors for HIV Infection • Ever being arrested (p<0.05) • Not always wearing condoms (p<0.01) • Used the internet to find male partner (p=0.07) • Having received money for anal intercourse (p=0.08)
Unmet prevention needs for MSM in Malawi • No water-based lubricants available in country • HIV prevention and education efforts limited to one NGO—active only in urban areas • National program has no MSM component • No “open” venue for MSM/Gay/Bisexual men to meet • Police harassment of venues and outreach workers • Cultural norms enforce marriage—hidden MSM risks
MSM Risk and Rights Contexts Vulnerability to HIV infection is dramatically increased where sex between men is criminalized - UNAIDS, 2006 Criminalization and homophobia limit MSM access to HIV prevention, information, commodities, treatment and care - USAID, 2004 Faced with legal or social sanction MSM are excluded, or exclude themselves from sexual health and welfare - UNAIDS, 2006
Structural Discrimination 85 UN Member states criminalize sex between consenting adults of the same gender More than half of all African States 10 States have death penalties for homosexual relations between consenting adults (Pakistan, Saudi Arabia, Iran, Nigeria, Sudan) Source: International Lesbian and Gay Association, April, 2007
Human Rights Argument for MSM Inclusion International Covenant on Civil and Political Rights (ICCPR) signed 1976, to which all African, most Asian, States are signatories Guarantees right “without distinction of any kind, such as race, color, sex, language, religion, political or other opinion, national or social origin, property, birth or other status” In 1994 the Human Rights Committee held that sexual orientation was a status protected under the ICCPR from discrimination, with reference to “sex” including “sexual orientation”
Conclusions • HIV epidemic spread among MSM is occurring in both high and low income settings in 2008 • MSM epidemics appear to be largely “dis-linked” from general population prevalence levels • Urgent need for MSM programs in prevention, treatment and care, surveillance
